A chalazion is a hard bump that forms on the eyelid.

A chalazion can form when the duct leading from a gland of the eyelid becomes blocked. This gland produces an oily substance that lubricates the margins of the eyelid and the front of the eye. When the duct becomes blocked, the oily substance can harden. This causes a chalazion to form near the edge of the eyelid. This condition can recur.
Factors that may increase your chance of a chalazion:
The initial symptom is a small swelling on the eyelid. It may look like a stye. It may or may not be painful. After a few days, the swelling on the eyelid often begins to harden. The bump grows slowly into a hard lump.
A chalazion can cause complications, though not often. Complications may include:
Your doctor will ask about your symptoms and medical history. An eye exam will be done. Rarely, a sample of fluid from the chalazion is taken and tested in a lab.
A chalazion will often disappear on its own. Treatment may include:
A warm compress is applied to the affected eyelid several times a day. Follow with gentle massage.
Corticosteroid is injected into the chalazion. This is done by an ophthalmologist, but is rarely required. Antibiotics may also be used if an infection develops.
An incision may be made near the chalazion to allow it to drain. The procedure is usually performed in the office with a local anesthetic. Surgery may be done if the chalazion does not respond to other treatments. It may also be considered if the chalazion is very large, grows rapidly, or causes vision problems.
